I had some misoto rose radish seeds from 2011 that sprouted beautifully this fall but other seeds from the same company and year are dead. I admit they were in supposed climate controlled storage for 3 months while we built our house. I was surprised the radishes still had life. Just wondering if I store them in cool location can they generally be used a second year?
I tested the seeds by dampening a paper towel and placing 10 seeds on it, then closing up in zip bag. If 6 sprouted then I had a 60% sprout rate. The radish were 80%. All the others were zero.
